I want to remove all special characters and spaces from a string and replace with an underscore.
The string is
var str = "hello world & hello universe";
I have this now which replaces only spaces:
The result I get is `hello_world_&_hello_universe`, but I would like to remove the special symbols as well.
I tried this `str.replace(/[^a-zA-Z0-9]\s/g, "_")` but this does not help.
